Oscillating tower design reaches more vertical and horizontal space than compact heaters, making it one of the few models users say genuinely heats an entire large room. High user ratings and a remote control set it apart.
Tower-style space heaters, and especially those that oscillate like this DeLonghi Ceramic Tower Heater model, are some of the best options for heating a large space like a larger bedroom or living room. Their radiant heat is capable of reaching more space both vertically and horizontally because of its size and functionality.
This model also had one of the highest user ratings among retail sites, with many users mentioning how quiet it ran, and singling out the utility of the remote control and digital display, which is a less common feature among the space heaters I researched.
Top pick from both Wired and The Spruce, with dual-axis oscillation, a working thermostat, and whisper-quiet operation. Checks every box better than any other heater tested across dozens of models.
Good Housekeeping's best overall pick and a perennial community favorite, whisper-quiet, compact, and backed by a 5-year warranty. Circulates warm air throughout a room in minutes despite its small size.
Good Housekeeping's best value pick raised a room's temperature 7°F in 30 minutes and runs as quietly as a refrigerator, all for around $35. Packs more features than heaters costing three times as much.
Wired's pick for best quiet heater runs below 40 dB on low, quieter than any other digital heater tested. Vornado's vortex technology pushes heat to the far corner of the room almost imperceptibly.
